COMMERCIAL    FERTILIZERS.  7 

The  West  Coast  Fertilizer  Co.,  which  was  registered  last  year,  is  out  of 
business  this  year,  but  some  of  its  goods  are  yet  on  the  market,  a  sample 
of  which  was  collected  and  analyzed  and  is  herein  reported. 

Following  the  requirements  of  Section  4  of  the  fertilizer  law,  which 
requires  that  an  inspection  be  made  between  July  1st  and  September 
1st,  an  inspection  covering  the  State  was  made  in  August.  Seventy-five 
samples  were  collected  on  this  inspection,  all  of  which  were  analyzed 
and  are  reported  in  this  bulletin,  with  one  exception,  a  sample  taken 
from  a  stock  of  only  two  bags,  and  for  this  reason  not  considered  a  rep- 
resentative sample.  In  addition  to  these  samples  collected  by  the 
inspector,  six  samples  have  been  sent  by  farmers  for  analysis  since  the 
last  bulletin  on  fertilizers  was  issued,  and  these  results  are  also  given. 

The  samples  included  in  this  report  may  be  classified  as  follows: 

Complete  Fertilizers 50 

Bone  Meal  and  Tankage - 12 

Nitrogenous  Superphosphates 4 

Nitrate  of  Soda .. 2 

Sulfate  of  Potash 2 

Bird  Guano __. 2 

Gypsum 2 

Thomas  Phosphate  Powder 3 

Blood 3 

Total _ _ 80 

These  80  samples  represent  54  registered  fertilizers,  fertilizing  mate- 
rials, and  special  formulas.  These  numbers  will  doubtless  impress  most 
readers  of  this  report  as  being  small  when  it  is  remembered  that  190 
brands  and  materials  have  been  registered;  and  so  they  are.  .Experi- 
ence has  shown  that  between  July  1st  and  September  1st  practically  all 
the  goods  found  on  the  market  are  remnants  of  the  preceding  spring 
trade.  The  law  does  not  prohibit  other  inspections,  and  the  State  will 
be  thoroughly  inspected  again  each  year  at  such  a  time  as  circumstances 
indicate  that  the  largest  amount  of  goods  will  be  found  on  the  market. 
The  plan  of  inspection  is  to  get  as  many  samples  as  possible  from  goods 
actually  on  the  market.  After  having  secured  samples  of  as  many 
brands  as  possible  in  this  way,  the  inspector  then  visits  the  factories  and 
endeavors  to  secure  samples  of  the  brands  not  found  in  the  hands  of 
agents.  Notwithstanding  this  procedure,  many  brands  are  registered 
which  are  not  found  on  the  market  or  in  the  factory.  The  fact  is  that 
the  trade  in  fertilizers  is  limited  to  a  few  standard  brands.  The  infer- 
ence is  that  many  of  the  brands  are  advertised  to  meet  the  supposed 
needs  of  farmers,  but  are  made  up  only  as  orders  are  received. 

Two  reports  will  be  issued  each  year.  The  first  will  give  the  results 
of  the  inspection  made  prior  to  September  1st,  and  the  second  the 
results  of  the  subsequent  inspections  made  during  the  winter  and  spring 
seasons.     The  reports  will  be  distributed  as  soon  after  the  analyses  are 


8  UNIVERSITY    OF    CALIFORNIA — EXPERIMENT    STATION. 

finished  as  it  is  possible  to  get  them  through  the  press.     The  first  may 
be  looked  for  about  December,  and  the  second  about  May  or  June. 

DEFICIENCIES. 

Section  4  of  the  fertilizer  law  provides  that  "  Whenever  the  analysis 
certified  by  the  said  Director  shall  show  a  deficiency  of  not  more  than 
one  fourth  of  one  per  cent  of  nitrogen,  or  one  per  cent  of  soluble  or 
available  phosphoric  acid,  or  one  half  of  one  per  cent  of  potash  soluble 
in  distilled  water,  the  statement  of  the  manufacturer  or  importer,  as 
required  in  section  one  of  this  Act,  shall  not  be  deemed  to  be  false  in 
the  meaning  of  this  Act." 

The  following  summary  gives  the  average  guaranteed  composition  of 
the  samples  containing  two  or  more  ingredients,  the  average  of  the 
analyses  of  the  same,  and  the  number  of  deficiencies  found: 

Average  of  Guaranteed  Composition. 

Available  Phosphoric  Acid 8.08% 

Insoluble  Phosphoric  Acid... ___ 2.07% 

Total  Phosphoric  Acid 11.62% 

Nitrogen 3.66% 

Potash 3.76% 

Average  Composition  of  the  above  Samples  as  shown  by  the  Analysis. 

Excess  above 
Guarantee. 

Available  Phosphoric  Acid 8.72%  0.64% 

Insoluble  Phosphoric  Acid 2.13%  0.06% 

Total  Phosphoric  Acid 11.98%  0.36% 

Nitrogen 3.92%  0.26% 

Potash 3.91%  0.15% 

Out  of  80  samples,  60  are  within  the  limits  of  deficiency  allowed  by 
law  in  all  the  ingredients,  although  some  fall  somewhat  below  the 
guarantee  in  one  or  more  ingredients.  Five  fall  below  the  legal  allow- 
ance in  available  phosphoric  acid,  nine  in  nitrogen,  and  eight  in  potash. 
Several  samples  have  a  shortage  in  one  or  more  ingredients  and  have  a 
compensating  excess  in  the  other  ingredient  or  ingredients,  so  that  the 
value  calculated  from  the  analysis  is  equal  to  or  greater  than  the  value 
calculated  upon  the  guarantee. 

The  average  value  for  all  the  samples  calculated  upon  the  guarantee 
is  $28.68,  while  the  average  value  calculated  upon  the  analysis  is  $30.21. 

In  estimated  value,  only  one  sample  is  deficient  in  an  amount  greater 
than  the  value  of  the  deficiencies  allowed  by  law. 

ANALYSES    FOR    CONSUMERS. 

Any  user  of  fertilizers  may,  by  paying  the  fee  specified  in  Section  4 
of  the  fertilizer  law,  have  a  sample  of  his  material  analyzed.     This  fee 


COMMERCIAL    FERTILIZERS.  9 

does  not  begin  to  pay  the  cost  of  the  analysis,  but  the  nominal  charge 
is  made  to  prevent  the  sending  of  samples  through  idle  curiosity,  as  is 
always  the  case  when  analyses  are  made  free  of  charge. 

The  sample  should  be  drawn  from  the  amount  of  fertilizer,  and  in 
the  manner  prescribed  by  Section  5  of  the  law,  and  whenever  possible 
it  should  be  drawn  in  the  presence  of  the  agent,  who  should  sign,  as  a 
witness,  the  certificate  given  below.  If  the  sample  is  not  drawn  in  the 
presence  of  the  agent,  it  should  be  done  in  the  presence  of  some  other 
person,  who  should  sign  the  certificate  as  a  witness.  Special  care  should 
be  exercised  to  thoroughly  mix  the  large  sample  before  drawing  the 
small  sample  to  send  to  the  Station.  This  is  absolutely  necessary  to 
obtain  a  trustworthy  result.  A  sample  filling  a  quart  fruit  jar  is  about 
the  proper  amount  to  send.  Consumers'  samples  will  be  given  prefer- 
ence and  the  results  reported  as  soon  as  possible.  The  sample  should 
be  sent  in  time  to  receive  the  report  before  the  fertilizer  is  used,  or  else 
the  bags  from  which  the  sample  is  taken  should  be  reserved  until  the 
report  is  received,  so  that  in  case  of  controversy  with  the  manufacturer 
an  official  sample  may  be  drawn. 

The  form  of  certificate  given  below  should  be  used  in  sending  a  sam- 
ple for  analysis.  Blank  forms  will  be  furnished  upon  application. 
When  more  than  one  sample  is  sent,  they  should  be  marked  in  some 
way  so  that  they  may  be  identified.  The  sample  should  be  sent  pre- 
paid, addressed  to  the  Fertilizer  Control,  Experiment  Station,  Berkeley, 
and  should  bear  the  name  and  address  of  the  sender.  Bank  checks  and 
money  orders  should  be  made  payable  to  "  The  Regents  of  the  University 
of  California."  Letters,  certificates,  and  remittances  should  not  be 
enclosed  with  the  samples,  but  mailed  separately.  When  the  report 
is  received,  a  tag  or  label  taken  from  one  of  the  bags  sampled  should 
at  once  be  sent  and  the  name  and  address  of  the  agent  from  whom  the 
goods  were  purchased  should  be  given.  Analyses  will  be  made  only  for 
those  who  purchase  fertilizers  for  their  own  use. 

CERTIFICATE    FOR    CONSUMER'S    ANALYSIS. 

E.  W.  Hilgard,  Director, 

Berkeley,  Calif. 

This  is  to  certify  that  I  am  not  a  dealer  in,  or  agent  for  the  sale  of 
any  fertilizer,  and  that  the  fertilizer,  a  sample  of  which  I  have  sent  you 

for  analysis,  was  purchased  by  me  _  _ ,190.    ,  for  my  own  use 

and  not  for  sale. 

I  further  certify  that  the  amount  purchased  was  . tons,  and 

that  the  sample  was  drawn  from packages  and  was  thoroughly 

mixed. 

Upon  receipt  of  the  analysis  from  you,  I  agree  to  furnish  you  with  a 
tag  or  label  taken  from  one  of  the  packages  sampled,  and  the  name  and

An  explanation  of  terms  used  in  reporting  fertilizer  analyses  was 
given  in  Bulletin  No.  157,  and  will  not  be  repeated  here.  The  text  of 
the  law  was  also  given  in  the  same  bulletin.  Those  who  have  not 
obtained  a  copy  of  the  bulletin  may  do  so  by  addressing  the  Director 
of  the  Experiment  Station,  Berkeley,  Calif. 

VALUATION   OF    FERTILIZERS. 

The  "agricultural  value"  and  the  "commercial  value"  of  fertilizing 
materials  are  not  synonymous  terms.  The  agricultural  value  of  a  fer- 
tilizer is  determined  by  the  increase  and  quality  produced  by  it  in  the 
crop.  The  commercial  value  of  a  fertilizer  is  determined  by  the  cost  of 
the  materials  which  enter  into  its  composition.  A  fertilizing  material 
may  have  a  low  agricultural  value  on  a  particular  soil  and  have  a  high 
commercial  value.  On  another  soil  the  same  material  may  have  a  high 
agricultural  value. 

Nitrate  of  soda,  at  present  one  of  the  cheapest  forms  of  nitrogen 
produces  on  some  crops  the  more  profitable  increase,  while  on  other 
crops  the  slower-acting  and  more  expensive  forms  produce  the  more 
profitable  increase. 

The  law  of  supply  and  demand  regulates  the  commercial  value  of 
fertilizing  materials,  the  general  agricultural  value  of  the  materials 
regulating  largely,  of  course,  the  general  demand  for  them. 

In  calculating  the  values  given  in  this  report,  the  Experiment  Station 
does  not  undertake  to  say  what  the  retail  prices  of  fertilizers  should  be 
in  this  State.  The  values  given  are  for  the  unmixed  raw  materials 
which  enter  into  the  fertilizer,  and  do  not  take  into  account  the  cost  of 
grinding,  mixing,  bagging,  insurance,  drayage,  agents'  commissions,  and 
other  expenses  of  the  manufacturer. 

The  schedule  of  values  used  is  given  below.  They  represent  as  nearly 
as  could  be  determined  the  prices  at  which  fertilizing  ingredients  in  raw 


COMMERCIAL    FERTILIZERS.  11 

materials  of  good  quality  could  be  bought  at  retail  for  cash  at  the  ware- 
house in  our  largest  markets  like  San  Francisco.  Quotations  were  called 
for  from  dealers,  but  they  varied  so  widely  that  it  was  very  difficult  to 
arrive  at  a  schedule  of  values  that  represent  the*  actual  market  condi- 
tions. Two  values  are  given  for  each  sample  analyzed,  one  calculated 
on  the  guarantee,  and  the  other  on  the  actual  analysis.  Even  if  the 
trade  values  are  not  absolutely  correct,  they  serve  as  a  basis  for  com- 
parison between  the  guarantee  and  the  analysis.

To  illustrate  the  method  of  calculating  the  value  of  a  fertilizer,  the 
following  example  is  given:

Analysis.  per  lb. 

Available  Phosphoric  Acid 8.00%  @  6     cents  =  $0.48 

Insoluble  Phosphoric  Acid 2.00  %  @  2%  cents  =    0.05 

Total  Phosphoric  Acid . .     10.00 

Nitrogen  in  Nitrates 1.50  %  @  15^  cents  =   0.23*4 

Nitrogen  in  Organic  Matter 2.50  %  @  VI %  cents  =   0.43%: 

Total  Nitrogen 4.00 

Potash  from  Sulfate _ 4.00  %  @    6     cents  =    0.24 

Value _ _ $1.44    per  100  lbs. 

$1.44  X  20  =  $28.80  per  ton. 

It  is  to  be  hoped  that  farmers  will  carefully  examine  the  analyses 
instead  of  looking  only  at  the  column  of  commercial  values.  The  agri- 
cultural value  of  a  fertilizer  depends  upon  the  amount  and  proportions 

*Fine  and  medium  bone  are  separated  by  a  sieve  with  50  meshes  to  the  inch;  fine  and 
medium  tankage  by  a  25-mesh  sieve;  and  fine  and  medium  Thomas  Phosphate  Powder  by  a 
100-mesh  sieve. 

t  This  method  of  giving  a  valuation  to  Thomas  Phosphate  Powder  is  temporary,  awaiting  the 
adoption  of  methods  by  the  Association  of  Official  Agricultural  Chemists. 


12  UNIVERSITY    OF    CALIFORNIA EXPERIMENT    STATION. 

of  the  essential  ingredients  contained  in  forms  available  to  plants,  and 
the  materials  from  which  they  are  derived.  The  value  calculated  upon 
the  analysis  may  be  greater  than  the  value  calculated  upon  the  guaran- 
tee, and  at  the  same  'time  one  ingredient  be  much  below  guarantee^ 
while  another  is  correspondingly  above  guarantee.  It  is  desirable  that 
the  fertilizer  be  as  evenly  mixed  as  possible. 

REPORT    OF   ANALYSES. 

The  following  table  gives  the  results  of  all  analyses  made  since  the 
last  report  was  published.  A  summary  has  already  been  made  relative 
to  the  standard  of  goods  analyzed.  It  may  be  stated  here  that  no  goods 
were  found  to  contain  materials  different  from  those  guaranteed,  except 
as  indicated  in  the  tables. 

Available  and  insoluble  phosphoric  acid  are  not  determined  in  bone 
tankage,  and  Thomas  Phosphate  Powder.  The  degree  of  the  fineness 
of  these  materials  is  determined  and  the  phosphoric  acid  divided  in  the 
ratio  of  the  fine  to  the  medium  material.  Fine  and  medium  bone  are 
separated  by  a  sieve  of  50  meshes  to  the  inch,  tankage  by  a  25-mesh 
sieve,  and  Thomas  Phosphate  Powder  by  a  100-mesh  sieve.  Nitrogen 
in  bone  and  tankage  is  also  divided  in  the  same  ratio.  These  divisions 
will  be  found  as  footnotes  to  the  table,  to  avoid  making  separate  tables 
for  the  materials  mentioned. 

It  may  be  added  here  that  it  is  required  that  all  fertilizers  put  on  the 
market  on  or  after  July  1st  of  this  year  carry  a  guarantee  of  the  per- 
centage of  nitrogen  in  its  different  forms;  that  is,  of  nitrogen  in  nitrates, 
in  ammonia  salts,  and  in  organic  matter.  Most  of  the  analyses 
reported  in  this  bulletin  are  of  samples  collected  from  goods  that  were 
put  on  the  market  before  July  1st,  and  consequently  have  a  guarantee 
of  the  total  nitrogen  only. 

Nitrogen  in  ammonia  salts  will  be  often  found  reported  when  nitrogen 
in  this  form  is  not  guaranteed.  In  such  cases  this  form  of  nitrogen  is 
produced  by  conversion  of  organic  nitrogen,  and  is  not  to  be  considered 
a  deviation  from  the  guarantee  of  materials  used.  This  form  is  not 
reported  separately  when  it  is  less  than  0.20  per  cent,  unless  nitrogen 
in  this  form  has  been  guaranteed. 

In  the  report  of  analyses,  the  percentage  of  chlorin  is  given  when  it 
exceeds  0.50  per  cent ;  and  when  there  is  an  amount  present  sufficient 
to  combine  with  half  or  more  of  the  potash,  the  potash  is  rated  as 
derived  from  potassium  chlorid  (muriate)  to  the  extent  of  the  combin- 
ing equivalent  of  the  chlorin,  whether  it  is  in  actual  combination  or 
not.  This  allowance  is  really  too  liberal,  and  may  seem  to  open  the 
way  for  the  dishonest  manufacturer  to  mix  muriate  with  his  sulfate ; 
but  it  is  assumed  that  the  manufacturers  are  honest,  and  that  when 
sulfate  is  claimed,  sulfate  has  been  used,  and  that  any  chlorin  present 


COMMERCIAL    FERTILIZERS.  13 

is  from  some  other  materials  used.  The  microscope  will,  however,  show 
whether  or  not  fraud  was  attempted.  Goods  may  be  made  practically 
free  from  chlorin,  as  will  be  seen  by  referring  to  the  table  of  analyses. 

The  following  abbreviations  are  used  to  designate  materials  used: 
Nit.  =  nitrate  of  soda;  Bl.  =  blood;  Bn.  =  bone;  Am.  Sul.  =  am- 
monium sulfate ;  Bat.  G.  =  bat  guano  ;  Bd.  G.  =  bird  guano;  Fs.  G.  = 
fish  guano*;  T.  =  tankage. 

*Fish  scrap.
